An embodiment of the present invention is T e ppe frame member sts oftWO side illustrated in the accompanying drawings, and members "I and 8,fashioned from flat metal. the views thereof are as follows: The lowerends of the side members 1 and 8 are Figure 1 is a fragmental isometricview of a 'inturned forming feet 9' and I0, which feet are ber B., I

' The upper portions of the side members 1 and 8 carry a platen 9 on ashaft III which is suitably supported. Disposed on the outer surface ofthe side member 8, is a mechanism for imparting step by step movement tothe platen. The

mechanism for operating the platen is that of applicant's aforesaidPatent No. 1,715,472.

At each end ofthe shaft 10 are the usual knobs II and I2 for rotatingthe platen by hand.

c on n'ected to'the side members-I and 8 in a positionto abut the crossbar 4 of'the lower" frame member A, and thus limit upward movement ofthe upper frame member B, is an angle bar l3 welded or otherwise securedto the side members 1 and 8. may; be observed in Figures land 4,this-bar 13: contacts the under side-of bar 4 when thecopy holderextended.

For 'unlatching the upper frame member for collapse, a. rod 2| ispivoted in the side members, land 8 and arranged along the rear marginof the bar I3. At the left hand endof the device, .as-viewed in Figures1 and 4, as well as in Figure 2, it will be observed that the rod 2|extends through the sidewall member Twhere at its outer end it isfastened to a crank 22 which normally is in substantialhorizontalposition, as

Pivoted at 22' to the outer mm. the: side member 1 is abell crank C,with oneleg 23 'extendingupwardly from. the pivot and provided vat-itsextremity with a'surface 24 constituting a thumb latch.f

The other .arm 25 of thebell crank extends downwardly in an'inclineddirection, from the,

Cooperating with the platen 9, to support copy against it for line byline advancement, is a. line guide member designated generally at D,includmg a cross. head 30 of substantially the same length as the platen9, and two depending hollow legs 31 and 32 arranged near the respectiveends of the cross head.

For cooperating with the legs 3| and 32, vertically disposed rods E andF having L-shaped feet are supported on the base I.

The rod E has-a. lateral horizontal foot portion 33 and a verticalportion 34, while the rod F has a lateral foot portion 35 and a verticalportion 35. The lateral foot portions 33 and 35 abut endwise within aclip I35 secured by screws I31 to the base along its front margin, ,forrocking 1 movement; Extending 1 rearwardly from the angle between theportions 33 and 34 of the rod E, is anintegral foot extension 31 havinga flattened end 38. In like manner, extending rearwardly from the angleof the rod F, is a similar foot extension 39 having a flattened end 40.

Supported for rocking movement along the rear margin of the base I is ashaft 4| having flattened portions 42 and. 43, which normally receivethe flattened ends 38 and of the extensions 31 and 39, of the rods E andF when the device is in operative position. The shaft 4| is supported inclips 44 and 45 fastened by screws 46 to theIbase, as may be observed inFigure '7. Fastened to the left hand end of the shaft 4|, as viewed inFigure 7, is a crank 41 which atits outer'end is pivotally connected asat 48 to the slotted bar 28.

At the other end or the base I, that is the vright'h'and end as viewed"in Figure 7, the shaft 4( carries a mutilated gear-49 in mesh with theteeth 50a of an arm 50 pivoted by means of a screw 5| to'this endv ofthe base. The arm 50 has an upstanding part provided with an outstandingend 52 for overlying the lever 53 pivoted at 54 to the base. The lever53, outwardlyof its fixed pivot 54, is pivoted to another pivoted leverwhich in turn carries at its free end a key. 55 adapted to be contactedby a finger of the typist to operate the platen in step by stepmovement. I

Pivoted to the end of the lever .53, adjacent the arm 50, is an uprightmember 56 which at its upper end carries a pin 56 entered in a slot 51in an actuating bar 58 which works the platen.

The depending legs 3| and 32, of the line guide structure D, at theirlower'ends encircle and receive the upright portions 34 and 36 of therods'E and 'F and are slidable along these por- The lower ends of thelegs 3| and 32 are provided with'elongated cylindricalportions 59 and 60for surrounding the. uprights of the rods E and F.

Pitvoted at 6|, to thelegs 3| and 320i theline I gui'de D, are lookingbars 62 extending along the legs. The lower ends of the bars 52 areshown as L-shaped,'as at '63, and normallyengage be observed in Figure2.

The cross head 30 is provided with aroller 63 the reduced ends 13 of theplungers passage which is mama-sea. nor ally, a ainst the platen 8 bymeans of the springs hereinafter-described."

The flattened ends 38 and 40, of the extensions 31 and 89 of the rodsEand F, are apertured as at 84 (lf'igure 8) with screws 65 passed throughthe aperture 84 in the flattened ends of the extensions 81 and 88 andthreaded into the base I.

vary the pressure of the roller 83 against the platen.

The effort exerted by'the springs 81 tends to maintain the roller 83 incontact with the platen.

8 to urge copy against the platen for advancement as the platen is givenstep by step rotative movement, as hereinafter described.

Guided in the upper ends of the side mem bers I and I, for horizontalmovement, are plungers l0 operatively connected to the upper ends oi thelevers i4 and I8, bypins ll carried by the piungersentered in notches I2iormed in the levers. The cross head is aperturedto'allow through thecross head.

The upper ends of the locking bars 82 have integral plates 14 in thepaths of-niovement of I the plungers l0. v

Normally the plungers :10 are retracted, as shown in Figure 6. As theplungers are moved outwardly, that is, to the left as viewed in Figure6, by swinging of the'levers' I4 and ii, the

reduced ends" or the plungers pass through-apertures in the crosshead 80and engage the plates 14 at the upper ends of the bars 82, thusbring-,ing the upper ends 'to the-right, as viewed in Figure-'2, and the lowerends to the left, which moves the lower ends out of register with-"theupper ends of the rods'E and F, thus 'unlatching the line guidestructureD,'ready for collapse.

Movement of'the plungers It to the left, as viewed in Figure 6, and tothe right as viewed in Figure 2, causes entry of the reduced ends 13 ofthe plungers' into the apertures in the line guide structure D, thusconnecting the line guide I a structure tothe upper frame member B ofthe device. As the levers and ii are rocked, as heretofore described,the'bar l8 connected'to the lower ends 01 thelevers l4 and", dropsbehind the rods 2' and 8 and remains behind therods' until the upperframe member Bis again ex tendedto operative position.- By reason of the,fact that the levers l4 and I8 remain tilted out] of engagement, byreason 'of the position. or the rod, behind the rods 2 and 8,'theplung'ers I0 are maintained in outward or projected position inconnection with the line guide" structure D to connect the line guidestructure to the upper frame member for simultaneous movement with it,downwardlyor upwardly, that is to say, into inoperative or operativeposition.

When the upper framemember is raised or extended, which is done by theoperator grasping the knobs l i and I2 and raising the upper frame 3structure, and as soon as the upper frame member reaches its uppermostposition, the springs 28 become effective to move the lower ends of thelevers I4 and I5 over the bar 4 thus latching the upper frame member inextended position. Movement of the levers in this manner retracts theplungers l0, whereupon the locking bars 62,

'w'ith'the upper framemeinbers v l The cross head 30 is provided withtwo endcarried b'yithe legs ti and, a: of the line guide deviceC,"byvirtue oithe action or spring I28 swing into normal vertical positionwith their lower ends against the upper ends of the vertical portions 34and 88 of the rods Eand F, thus latching the line guide deviceineictended position. r

I It will be observed that the upset-isms member and the line guidedevice are. raised and lowered simultaneously.v The engagement oi theplungers 18 with the line guide device raises it wise -extensible guides18 and 15,, which arefcorrespondingly grooved, as may be observed inFigure 5, and =whichare' retained against the. rear surface of the crosshead 80 by aholding clip 18' extending-substantially lengthwise oi thecross head. The outer ends of the members 15 and 18' are provided withknobs 11 wherebymovement orthesemembers may be easily accomplished.

d For supporting copy moved upwiirdly by the platen, a skeletonstructure is provided, which is adjustable forwardly and backwardly, asthe character oi the copy might require; 'j e Referring to Figures 1 and6;.a honow' b if- 1a. having .a polygonal interior is, oscillatablymounted in the'upper ends of the? members-'1 and 8. Endwisemovableinthefends of the bar 18, are. polygonally shaped ibars 1.9 havingthe'ir to J outer ends extending outwardly of the members l and 8. Theinner ends of thebarslsj aref provided with suitablestops,fsuch as'pins,.to

limit outward movement within the, bar "18.; Y

The outer endsof thepolygonally shaped bars 19 carry angularly shapedend pieces 80,which endpiecesare provided with telescoping bars 8l' and,82 so arranged that thepolygonalbar's "l8 may be moved outwardly totheir limit of travel with the b'ars8l and 82 still intele'scopingengag'ement, to provide an elongated copy guide greater in extent. thanthe length of the cross head 80 oi the line guide device C. The cross,head 80 is provided with a handle 83 whereby the cross head and theroller 83 may be pulled away from the platen for insertion fof copybetween the roller and the platembe the copy a stenograp'her's notebookor a single sheet of paper.

Copy inserted between theroller and the platen will, on actuation of theplaten, be advanced in step by step manner in accordance with theadjustment ofthe amount of feed of'the platen.

Copy may be-suspended in front of the typist, without engagingyitbetween the roller 88 and the platen, by means of a hinged member '84which is secured to the front face of the cross bar ,bysuitable hingesand, tensioned by springs The 'means'for imparting step by step 'move-,

.ment to the platen 8 are the means illustrated in applicants'Patent No.1,715,472, and herein illustrated for convenience, as follows: i

' At one end of the shaft ID of the platen, herein illustrated as theright hand end looking at ,the machine as illustrated in Figure 4, is aratchet the shaft i 0.

Between the end member 8 and the ratchet wheel 86, a plate 81 isoscillatable on the shaft;

This plate is provided ,with a plurality or depressions or. holes 88,arranged on a radius, with which cooperates a depression 89- fprmecl inone end of a. spring 90 secured by bolts9l to the end member 8. Theplate ,8! is .oscillatable about its wheel 86 secured by means of setscrews867to shaft by means of a lever 82 so that any one oi 7 normallymaintain the point of the pawl to the left, as viewed in Figure 5, thatis.in position to engage a tooth of the ratchet 86.

The ofiset 93 of the lever 92 is so fashioned that thepoint of the pawl94 normally bears against this ofiset behind the lever 92, as shown inFigure 5. ,Friie angular position of the lever 92, from that shown inFigure 5, to a position in which the detent 89 engages the right-handdepression 88 in the plate 81, controls the number of teeth of theratchet disposed to action by the pawl point. As the parts are arrangedin Figure 5, downward movement of the plate 58 will move thepawldownwardly, with its point engaging the tooth immediately beneaththe ofiset portion 93 of the lever. The plate 58 is moved the samedistance, every time, by actuation of the key 55.

To adjust the platen for two-stage movement, the lever 92 would be swungclockwise, so that the detent 89 would engage the middle depression 88which would then shift theoifset portion 93 of the lever downwardly onespace covering the tooth which otherwise would be engaged by the pawlwith the lever in the position shown in Figure 5, limiting theadvancement of the pawl to a two-stage movement.

A clicking pawl 91 is pivoted at 98 and has an outstanding latch 99adapted to rest against the teeth of the ratchet when the pawl islowered. In order to maintain the pawl out of clicking engagement, alever I00 having an end IN adapted to engage with the pawl is suitablypivoted behind the ratchet and has an extremity available formanipulation by the operator. With the clicking pawl in the positionshown in Figure 5, there would be no click apparent as the platen isrotated. With the lever I00 swung in counter clockwisedirection, tobring the latch 99 against the ratchet teeth, then clicking would occurwhen the platen is rotated as the spring H5 tends to urge the latch 99against the ratchet teeth when the lever Hill is swung incounterclockwise direction moving its projection llll out of the way ofthe lower end of the pawl 91.

Figure 5 illustrates the arrangement of parts with the platen set toadvance the distance of three ratchet teeth per movement, and withoutany copy between the roller 63 and the platen.

The device, when extended for use, has the appearance shown in Figure 4.The bars 8| and 82 may be endwise adjustable to accommodate the width ofthe copy used. If this is copy to be advanced in step with the platen,then it is inserted between the platen and the roller 63 and alignedwith the upper margin of the cross head 30, which margin serves as aline guide. If the copy is not to be moved, then it may be supportedbetween the cross head 38 and the member 84 and suspended in verticalposition in front of the typist.

In order to extend the line guide beyond the length of the cross head39, the members I4 and 15 may be pulled out, as indicated by dottedlines in Figure 4, to afiord a line guide comparable with the width ofthe copy utilized.

The copy holder may be collapsed as follows:

With the copy holder extended, as illustrated in Figure 4, and with thetelescoping rods 8| and as viewed in Figure 2, pressure of the rollel 82in full line position and the extensible guides 14 and I5 housed behindthe cross head 30, the operator moves the thumb latch 24 backwardly, asviewed in Figure 4, and to the left, as viewed in Figure 2. Suchmovement, first of all, raises the slotted bar 28 thus rocking the shaft4| and through it raising the overlying ends of the flattened endportions of the extensions 31 and 39 of the rods E and F, to move them ashort distance away from the platen, such for example as to the dottedline position of Figure 2. Such movement relieves whatever bindingengagement there may be between the cylindrical portions 59 and 60 ofthe legs 3| and 32 and the rodsE and F. When the bell crank C has beenmoved to bring the end of the pin 26 against the cran against the platenhas been relieved. Continued movement then rocks the rod 2| to swing thecrank 29 against the lower ends of the levers l4 and I5, which moves thelower ends and the connected bar l8 away from the bar 4 and at the sametime projects the plungers' 10 to unlatch the bars 62 of the line guidedevice from contact with the upper ends of the upright portions 34 and36 of the rods E and F. As soon as the lower ends of the levers l4 andI5 are moved away from the bar 4, the upper frame member B dropsslightly thus bringing the lower ends of the levers l4 and I5 behind thebar for maintaining the plungers l8 projected and connecting the lineguide device with the upper frame member B. The operator then pushes theupper frame member down to the dotted line position of Figure 2,collapsing it together with the line guide device. As the upper framemember B is collapsed, that is, moved downwardly to inoperativeposition, the bar 58 slides downwardly with it, which it may do, as thepin 56 carried by the link 56 rides in the slot 51 of the bar 58.

As the shaft 4| is oscillated, in the manner just described, themutilated gear 49 rocks the arm 50 to depress the lower end of the bar56, thus imparting slight rotative movement to the platen, whichmovement may have some effect in moving the roller 63 away from theplaten the instant the plungers 10 are projected.

To extend the holder, all that is necessary to be done is to grasp theknobs l I and I2 and raise the upper frame member until upward movementis stopped by engagement of the bar l3 of the upper frame member againstthe bar 4 of the lower frame member. When this contact is established,the lower ends of the levers i4 and I5 swing inwardly over the bar 4, byaction of the springs 20, thus latching the upper frame member inextended position, and such lever movemerit retracts the plungers l0,whereupon the springs 61 urge the roller 63 against the platen 9 withsufficient frictional engagement to hold copy between the roller and theplaten.

'If desired, a hood may be applied over the platen and the rear side ofthe upper frame mem ber. Such a hoodis herein illustrated at I82. Itmaybe secured in position by screws or any other manner, and may befinished as desired.

that a stenographers book may be readily inmanufactured economically, ona production 7 basis.

The upper frame member latches automatically when it is moved to fullyextended position, and may be lowered or housed by manipulation of asingle member, to wit, the'thumb latch 24.

The bar 58 is normally maintained in upward position by means of aspring I03 connected at one end to the bar and at the other end to a pinI 04 on the end member 8 of the upper frame member. V

Figure 8 shows the manner of movement of the extensions 31 and 80 of therods E and F in accordance with oscillatory movement of the shaft H, asheretofore described.

Springs I maybe applied to the locking bars 62 to normally urge theminto locking relation with the bars E and F, when the line guidestructure D is'in raised position.

In order to secure the skeleton structure in angularly adjusted positionwith reference to the center of the bar 18, as an axis, a lever I 05 ispivoted at. I06 to the outer surface of the side member 1, and is'provided with a curved end I01 shaped to conform to the projecting endof bar I8. A trigger I08 is pivoted at I08 to the member I and isarranged with a cam shaped end IIO against the lever I05 in position tomove its curved end I01 into tight frictional contact with the bar I8.

The hinged member 84 is provided to hold a stenographers note book inplace. When a book is inserted to be read without spacing the book asthe shorthandnotations are typed, the book is held between the tworollers and the pages to be typed hang outside of the member 84. Whenthe book is to be spaced, line for line, it is held between the rollers,with the pages to be copied behind the member 84, the latter serving asa line guide. When the book is not to be spaced, the roller 8 remainsinactive. When the book is to be spaced, the roller 9 is spaced byactuation of the levers 53, 58, and 58.
